Environment
Liquid chromatography equipment is a widely spread analytical tool used to separate,
identify and quantify components in a liquid mixture for purity and content. The equipment
utilizes reciprocating pumps to pass pressurized liquid solvents with sample mixtures
through a column filled with a solid material. Positive displacement pumps use
Omniseal® spring-energized seals to optimize performance and equipment longevity.

Challenge
Since each customer's reciprocating pumps are unique, they need seals that are custom
designed to accommodate specific pressure ranges and dimensional specifications. Seals
must also be able to handle various liquid solvents and environments. Customers want
improved cycle times up to two million cycles to improve the time between maintenancesor the overall lifetime of their machines.. They are looking for higher pressures and smallerseals with improved performance.
Ultra High Performance Liquid Chromatography (UHPLC) equipment utilize highoperational pressure up to 1400 bar or 20,000 psi and above. Due to the high pressuresutilized, critical sealing is necessary in the plunger pumps to ensure analysis accuracy. Seals
are important for challenges such as chemical resistance, friction and wear control. With
growing regulation on the use of PFAS material like fluoropolymers, OEMs are requiring
parts deprived of PFAS, making the application even more challenging, in particular on thefriction management.

Solution
Omniseal Solutions provides custom seals for
precision fit and has compounded and designed
severalspecialized

PFAS-Free*

materials

towithstand harsh solvents and improve wear.
The right combination of material and design for

the equipment application and pressure range are
the key to the wear and overall equipment
performance. Physical models of our materials
allow predictive simulation, enabling the selectionof the right design.

At the Kontich, Belgium, research and development center, critical life and wear testingstudies are performed in customers' reciprocating pumps, which ensure equipment
performance for longevity and quality. Maintenance cycles can be reduced with the rightalternative material and shape that is formulated based on our design and development
experience in high pressure and solvent testing.

Benefits•

PFAS-Free*solution,

removing

concernonpotential subsequent supply chain modifications•

Chemical resistance and compatibility with saline

solutions and a wide range of media and solvents•

Low friction and wear for long life•

Continuous performance under high pressures•

Smaller seal designs withstand higher pressure*PFAS-Free here means we do not intentionallyadd PFAS material in the product, but does notexclude the possibility of traces, as these materials
are common in the environment.
